The demonstrations of moving silhouette images continued through April. The system consisted of 30 lines and 12.5 pictures per second. | | June | 13 | Charles Francis Jenkins achieves the first synchronized transmission of a moving silhouette (shadowgraphs) and sound, using 48 lines, and a mechanical system. A 10-minute movie of a miniature windmill in motion was sent across 8 kilometers from Anacostia to Washington, DC. The images were viewed by representatives of the National Bureau of Standards, the United States Navy, the Department of Commerce, and others. Jenkins termed this "the first public demonstration of radiovision". | | July | 13 | Vladimir Zworykin applies for a patent for color television. | | c.
